the waterproof membrane is arranged between the high-pitch horn and the low-pitch horn of the high-pitch part and is positioned at one end of the low-pitch horn, so that water flow is prevented from permeating into the high-pitch part from the low-pitch horn;

the waterproof elastic wave is arranged at the opening of the bass part and used for blocking water flow at the edge of the opening of the bass part, and a circular hole is formed in the center of the waterproof elastic wave and is a part of the sound channel;

the waterproof horn is arranged at the center of the waterproof elastic wave, extends to the outside of the waterproof elastic wave along the axial direction, and the outer end of the waterproof horn radially shields the circular hole and is used for blocking splashing and impacting water flow for the circular hole, wherein a gap is formed between the waterproof horn and the circular hole and is used as a part of a sound channel.

Preferably, the waterproof horn is supported on the low horn by a pair of support tubes.

Preferably, one end of the bass horn facing outwards is horn-shaped, and the inner wall surface of the bass horn is provided with an inner inserting hole for inserting the inner end of the support tube.

Preferably, the waterproof horn surface is provided with an outer inserting hole for inserting the outer side end corresponding to the outer side top end of the supporting tube.

Preferably, the low horn outer end is in contact with the circular hole inner wall.

The horn type high-pitch coaxial full-frequency loudspeaker realizes good waterproof performance through the matching of the waterproof membrane, the waterproof horn and the waterproof elastic wave, and particularly has more remarkable waterproof effect on high-pitch parts.

Fig. 2 is a schematic exploded view of a horn-type high-pitch coaxial full-range speaker according to the present invention.

The implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model provides a horn type high-pitch coaxial full-frequency loudspeaker, which comprises:

the high-pitched sound box comprises a high-pitched sound part 1 and a low-pitched sound part 2, wherein the high-pitched sound part 1 and the low-pitched sound part 2 are connected and fixed, a sound channel is formed between the high-pitched sound part 1 and the low-pitched sound part 2, the low-pitched sound part 2 is provided with a low-pitched horn 5, and the inner cavity of the low-pitched sound part is a part of the sound channel;

a waterproof film 3 which is provided between the high-pitched horn 4 and the low-pitched horn 5 of the high-pitched part 1 and is located at one end of the low-pitched horn 5, and prevents water from infiltrating into the high-pitched part 1 from the low-pitched horn 5;

a waterproof elastic wave 6 which is arranged at the opening of the bass part 2 and used for blocking the water flow at the edge of the opening of the bass part 2, wherein a circular hole is formed in the center of the waterproof elastic wave and is a part of the sound channel;

a waterproof horn 7 disposed at the center of the waterproof shockwave 6, extending axially to the outside of the waterproof shockwave 6, the outer end of the waterproof horn 7 radially shielding the circular hole for blocking splashed and impacted water flow for the circular hole, wherein a space is formed between the waterproof horn 7 and the circular hole as a part of the sound channel, the outer end of the low-tone horn 5 is in contact with the inner wall of the circular hole, it should be noted that the outer end of the low-tone horn 5 can be connected with the inner wall of the circular hole to form a whole, thereby realizing seamless connection of the two, improving waterproof performance, and enhancing stability, the waterproof horn 7 is supported on the low-tone horn 5 through a pair of supporting tubes 8, wherein the outward end of the low-tone horn 5 is horn-shaped, the inner wall surface thereof is provided with an inner inserting hole for inserting the inner end of the supporting tube 8, the surface of the waterproof horn 7 is provided with an outer inserting hole for inserting the outer end corresponding to the outer end of the supporting tube 8, so that the two ends of the supporting tube 8 are respectively inserted into the inner inserting hole and the outer inserting hole to realize effective fixation and connection.

The horn type high pitch coaxial full-frequency loudspeaker is characterized in that the horn type high pitch coaxial full-frequency loudspeaker adopts the waterproof elastic wave 6 and the waterproof horn 7 to prevent water flow from being sprayed and impacted in the front and the side, so that the effective waterproof effect on the low pitch part 2 is realized, meanwhile, the low pitch part 2 is separated from the high pitch part 1 by matching with the waterproof membrane 3, so that the permeated water flow is prevented from entering the high pitch part 1 from the low pitch part 2, the waterproof performance of the high pitch part 1 is further improved, therefore, the proper horn type high pitch coaxial full-frequency loudspeaker has excellent waterproof performance integrally, and can achieve 5-6 levels of waterproof applied to automobiles and boats.

It should be noted that the waterproof horn 7 has a function in addition to the waterproof function, that is, the shape and profile of the waterproof horn 7 can be designed, the shape of the sound channel of the tweeter unit 1 and the sectional area thereof can be changed to realize the design of the horn tweeter performance parameters, and the active design of the horn tweeter performance parameters is realized, whereas the existing horn tweeter unit 1 has no way to design the active performance parameters of the opening section of the tweeter horn because the waterproof horn 7 is not arranged, and the active design becomes possible because of the occurrence of the waterproof horn.
